What counts as a good ROAS on Amazon?

How it's calculated: Clicks = Investment ÷ CPC · Conversions = Clicks × Conversion rate · Revenue = Conversions × Average order value · Cost/conversion = Investment ÷ Conversions · Net profit = Revenue − Investment · ROAS = Revenue ÷ Investment.

! Context matters more than the number

A "good", "average" or "poor" ROAS depends entirely on your business model. A company with high profit margins can be profitable with a lower ROAS, while a business with tighter margins may need a much higher return just to break even.

That's why ROAS should always be read alongside other metrics — particularly Customer Acquisition Cost (CAC) and Customer Lifetime Value (LTV). This calculator treats the average order value as pure revenue; Amazon's referral fees and fulfillment costs are not subtracted here, so real margin will be lower than the figures shown.

ROAS also plays a key role in automation: platforms increasingly offer Target ROAS-style bidding strategies, using machine learning to optimize campaigns around the return you want — letting advertisers scale spend while protecting profitability.

The ranges shown here are indicative only — they depend on your sector, your specific account, and your company's margin. Because of this, treat them as a general guide and consult a specialist where possible, since you should also factor in your break-even ROAS: the minimum return needed just to cover costs before turning any profit.
